RAIL-ANCHOR.

To (ZZZ whom it may concern:

Be it known that I, ROBERT E. BELKNAP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Rail-Anchors, of which the following is a specification.

This invention relates to rail anchors or anti-creepers for rails.

This application is a division of an application filed by me June 23, 1913, Serial N 0. 775,172 which resulted in Patent #1,228,171, dated May 29, 1917.

One of the objects of this invention is to provide an improved anchor wherein the base of the rail is gripped on both sides of the web.

Another object is to provide a simplified form of such an anchor which may be readily applied to rails already in place.

Another object is to provide an anchor wherein the load of creepage is distributed to the portions of the rail most capable of resisting the forces applied.

Other objects and advantages of-the invention will hereinafter appear.

In the accompanying drawing, Figure 1 is an end view of one form of the rail anchor of this invention in place. Fig. 2 is a side elevation of the anchor of Fig.1. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig. 4 is a modification of the anchor disclosed in Fig. 1. Fig. 5 is an end view of another form of anchor embodying this in vention. Fig. 6 is a side elevation of the anchor of Fig. 5. Fig. 7 is an end view of still another form of anchor in accordance with this invention. and Fig. 8 is a section on the line 8-8 of Fig. 7.

In the embodiment of this invention disclosed in Figs. 1, 2 and 3, the rail A rests upon the top of ties B to which it may be secured in the usual manner by tie plates and spikes or screws. The anchor or anticreeper comprises a body 10, which, on its upper surface, is provided with a lower jaw 10. According to the preferred construction, this jaw is adapted to engage and grip the bottom surface of the rail base at a point substantially below the web. Extending from the body 10 and cooperating with the lower jaw 10 are two upper jaws 11, one on each side of the web of the rail and each having a gripping surface 11 engaging and Specification of letters Patent.

gripping the top surface of the rail base. Depending from the body 10 and extending in advance of the jaws is a leg 10, which is adapted to abut a tie some distance below the jaws to tilt the anchor in a substantially vertical plane when the rail starts to creep. The form and dispositoin of the depending leg 10 is such that it normally biases the jaws to grip the rail base, and when it is caused to engage the tie by the movement of the rail, the entire anchor is tilted, causing the jaws to increase their bite or grip upon the base of the rail, to prevent further relative movement between the rail and tie.

If desired, in order to increase the biting or gripping action of the jaws upon the rail base, the jaws may be roughened or corrugated, or may be provided with teeth 11 and 10, as shown in Fig. 4.

In the construction shown in Figs. 5 and 6 the body of the anchor 19 is provided with a lower jaw 23 and an upper jaw 20, which embrace between them the base of the rail in a manner similar to that of the jaw 10 and I one of the jaws 11 of the construction shown in Fig. 1. There is also provided a depending leg 24 for engaging the tie in advance of and some distance below the gripping jaws to normally bias the anchor and to increase the gripping action of the jaws when the creepage of the rail causes the leg to abut a tie. anchor in place, especially when the leg 24 is not against a' tie, and to provide for additional gripping action, a second jaw or clip 21 is made to embrace or overlie the oppo site edge of the rail base. This supplemental holding member or jaw has an opening fitting over a square projection 19*, extending from the body 19 of the anchor, as clearly indicated in Figs. 5 and 6. A pin 22, extending through an opening in the projection 19 serves to prevent the anchor frolm being jarred loose, and holds it to the ra1 In Figs. 7 and 8 is shown a modified construction wherein similar jaws are provided on each side of the web, the jaws when in place being interlocked beneath the rail base. As shown the body portion has two practically similar interlocking sections 12 arranged to slide upon each other when being applied to the rail and to be secured In order to more positively hold the ends and said body portion Each section has an against displacement.

a jaw and the right extension 13 forming hand section of Fig. 7 has a horizontal extension 14 on which is formed a bearing surface or jaw 14?. This extension which is a little more than a semi-circle in crosssection is adapted to fit in a horizontal socket formed in anextension 12 of the left hand section. This latter section is also provided near its lower end with a T-shaped socket 12 adapted to receive an extension 12 of the right'hand section of the anticreeper, such extension being also substantially T-shaped in cross-section as illustrated in Fig. 8. This extension is adapted to slide in said slot and in order that the parts may position with a suiiicient force to prevent displacement, I provide such extension with a small projecting point 12 adapted to engage a depression or cavity 12 in the base of the slot.

What I claim is j 1. An anti-creeper for rails, comprising a body having an upward projection to engage the inner portion of the bottom face of a rail base and having a pair of jaws, one extending over each edge of the base to grip the top side thereof.
